A defective rhyme is a fault in serious verse—it is a crime in comic. It is no sin to be ignorant of Greek or Latin, but it is worse than a blunder, under such circumstances, to quote them—and quote them incorrectly. In the same way, one is not compelled to write comic verse, but if he does write it, and cannot do so correctly, he deserves severe handling.
One of the leading characteristics of this style is dexterous rhyming—and the legerdemain must be effected with genuine coin, not dumps. In the very degree that clever composite rhyming assists in making the verse sparkling and effective, it must bear the closest scrutiny and analysation—must be real Moet, not gooseberry.
All, then, that has been said with regard to serious verse applies with double force to the lighter form of _vers de société_. According to the definition of Mr Frederick Locker, no mean authority, _vers de société_ should be "short, elegant, refined, and fanciful, not seldom distinguished by chastened sentiment, and often playful. The tone should not be pitched high; it should be idiomatic, and rather in the conversational key; the rhythm should be crisp and sparkling, and the rhyme frequent, and never forced, while the entire poem should be marked by tasteful moderation, high finish, and completeness: _for however trivial the subject-matter may be,—indeed, rather in proportion to its triviality,—subordination to the rules of composition, and perfection of execution, should be strictly enforced_."
Let me entreat the reader to bear that italicised sentence in memory when writing any style of verse, but most especially when he essays the comic or burlesque.
No precedent for laxity can be pleaded because the poets who have at times indulged in such trifling, have therein availed themselves of the licenses which they originally took out for loftier writing. _Non semper arcum tendit Apollo_, and the poet may be excused for striking his lyre with careless fingers. But we, who do not pretend to possess lyres, must be careful about the fingering of our kits. Apollo's slackened bow offers no precedent for the popgun of the poetaster.
As I have already said, much of the merit of this style depends on the scintillations, so to speak, of its rhymes. They must therefore be perfect. When Butler wrote the much-quoted couplet:—
